2.37.1 Relay-address configuration
To apply the relay-address for the IED, the user should set ON for scheme switch [RYID-EN].
(i) Address configuration
The user should set relay-addresses for the respective IEDs. Figure 2.37-1 (a) shows the relay-
address number for terminals A and B; Figure 2.37-1 (c) shows for three-terminals A, B, and C
on star network. With regard to the relay-address number, 64 unique addresses (0 to 63) are
provided for the network.

ID numbering for two-terminals
For two-terminal mode (Figure 2.37-1 a), an IED at terminal A is required to set 0 for setting
[LOCAL_RYID]; the user should set 1 for both settings [CH1_RYID] and [CH2_RYID]. Another
IED at terminal B should be set 1 for setting [LOCAL_RYID]; then 0 for both settings
[CH1_RYID] and [CH2_RYID]. Do not touch the [CH*_RYID] if one of the settings need not
operate (zero (0) is set as default).
Three-terminal application
As for setting for the relay-addresses in the star network in Figure 2.37-1 (c), the user should
pick respective relay-address numbers at remote terminals; then set them for the settings
[CH1_RYID] and [CH2_RYID].
